Application filed March 2, 1922. Serial No. 540,428.

My invention relates to improvements in building forms and it more especially con;- sists oi? the features here-utter pointed out in the claims. a

The purpose of my invention is to provide torm units which may be v used in various combinations in building monolithic walls of concrete; in forming the outer face otthe wall to simulate brick or any other desired configuration; in forming the outer surface of the wall offiner texture, color-ed in any manner deemed best for aesthetic reasons etc, and forming the inner portion ofthe wall of coarser material; in providing means for holding the inner and outer form units in an easily adjustable relation to insure the proper horizontal and vertical alignment of the wall; that provides means for forming interior and exterior corners, window openings etc. that provides means for continuing the exterior design in an unbroken manner except for wall openings; and that provides form units which may be made of cast or stamped materials,

With these and other ends in view, I illustrate in the accompanying drawings such instances of adaptation as will disclose the broad underlying featureswithout limiting myself to the specific details shown thereon or described herein.

In practically carrying out myinvention I may use the exemplificationsshown or any substantial equivalent variation therefrom without departing from the broad spirit of my invention.

The inside and outside parts ofa form unit are relatively thin cast aluminum or other. stamped material plates 1 and 2. The outer plate has inwardly projecting hori zontal ribs 3, 1, 5, 6 and 7 and vertical 8 and 9. These ribs form corresponding brick grooves in the wall as. shown along the bottom ofFig. 4. The ends of this outer part 1 are formed with notches 10 which are a half-brick in length terminating These form units interconnect at the ends as shown in Fig. 1, the cooperating units being shown in dotted lines. In order to. make these parts properly join in end to end relation ribs 4 and 6 are omitted at 11 but are continuous at 12 and rib 5 is shortened'at both ends at 13 and 14. This allows theprojecting' end '15 to abut the rib "8 at the. right hand end of thesame courseand the projection 16 similarly abuts a rib 8-at the right: hand'end of the lower course. The omitted ribs 13 and'14 being on opposite upper and lower edges. of a brick compensate forv each other.

ribs

This outer part 1 is provided with con necting ears 17 and 18. These align with each other as the parts are assembled end to end along the entire stretch of a wall. Premovable pins 19 pass through holes in the ears 17 and 18 and serve to hold adjacent parts connected to each other.

Along the bottom of part 1 a series of pro jections or toes 20 are formed. These set into the vertical grooves which are formed in the completed wall immediately below, as shown in Fig. 4. Along the top edge pro jections 21 are formed for the clamps 22. These projections are rounding on top, as at 28, Fig. 8, and they may have side'fingers 24 which serve to hold the clamps in position against displacement lengthwise of the wall.

The inside units 2 are simply flat plates with top and bottom ribs 25 and interior vertical stiffening ribs 26. These plates along their upper edges also have projections 2 with side fingers 24 similar to the corresponding projections on the units 1. lVhen the type of short clamp 22 shown in Fig. 5 is used, tie-rods 27 connect the interior and exterior parts 1 and 2, and hold them in place with the lower ribs 25 and 7 resting in the grooves formed by the uppermost ribs of both parts 3 and 25 as shown in Fig. 5 and flanges 51 and 52 resting against the finished wall surface.

The clamps 22 shown in Figs. 5 and 8 and the clamp 64 shown in Fig. 11 function in the same way. They serve to hold the sides 1 and 2 in a definite spaced apart relation at their upper edge. They hear a pivoted relation to the sides 1 and 2 which permits of rapid and easy adjustn'ient' without disturbing their position with respect to each other. The upper edge of these plates or form units are held the proper distance apart by the clamp body alone and not by theadjusting screws 28, 81 or 56. By reason of this construction an inexperienced workman cannot make the'wall of varying width and the screws referred to permit of almost instantaneous vertical and horizontal alignment of the wall. I

Each of the clamps 22 in Fig. 5 has two set screws 28 which are threaded in the depending portions 29 of the clamps. Lugs 54 of Figs. 5 and 8 and 65 of Fig. 11 form limit stops for the upper edges of the plates 1 and 2. Between these lugs and the depending arms pivot points are formed as shown in Fig. 8 on which the clamps are free to rock. These pivot points rest on rounded ends 23 of projections 21, also shown in F ig..

8. The clamps are'held on the rounded ends 23 against movementlengthwise of the plates 1 and 2 by projections 24 which occur on each side of the clamp body.

In the clamps 22 shown in Fig. 8, the depending portions 30 are longer than the procomprise a wall -wall at its outer jections 29 shown in Fig. 5. They terminate below the middle of the form units 1 and 2, thus if desired, eliminating the tie outside 270 degree unit 83 in Fig. 18. The

units 32 are provided with ears 84that cooperate with ears 18 of the unit 1, and ears 35 that cooperate with cars 17 of the unit 1 while the corner unit 33 has ears 36 that cooperate with ears 18 and ears 37 which cooperate with ears 17 of unit 1, thus making the several units entirely cooperative in meeting any practical. condition that may arise.

In some cases, or whenever desired, an L shaped exterior corner unit 38, Fig. 17 may be used instead of the corner unit 33 shown in Fig. 18, or as another alternative the inside corner expedient shown in Fig. 9 can be used for exteriors by having units 1 formed with angle projections similar to those formed on inner plate units 39 at 40 with the brick notches 10 omitted. .hese projections serve to form abutmcnts for the clamp 41. If a further variation is desired the corner unit 38 Fig. 18 may he rigidly secured to one of the exterior units 1 and by means of a pin 19 attached to another unit around the corner. In some cases when a short unit is used alone it may be somewhat diificult to easily align or square the corner but with one leg longer than the other as shown in Fig. 17 this diliicultv disappears. I i

In forming window or other openings the units 42 and 43 respectively right. hand and left hand, shown. in Fig. 12 are used. These port-ion 44 which carries the brick facing up to the window frames. Space for such frames is provided by an otl set portion 45. In order that these units are held in place while the'concrete is being filled in, the outer end has notches 46 which pass over the len thwise ribs 4. 6 and 7 of units 1 shown in Fig. 14, and the 'ver* tical ribs 9 of units 1 serve to hold the units 42 and 43 from movement lengthwise of the surface and the clamps 47 attached to the inner plates 2 serve to hold units 42 and 48 in place at the inner surface of the wall. In Fig. 14 the units 1 and 2 are shown in dotted lines. Notches 48 are formed to accommodate ribs 25 of the inner units 2.

The outer units 1 are held in sequential relation across wall openings by means of a suitable bar 49 that has holes correspond ing to'the position of the ears 1? and 18 to receive pins 19 and the inner units 2 may be Jul iiU

llii

held'by clamps 22with any suitable wooden blocking (not shown) between these units and the outer ones. Reverting, to Fig. 17, the corner unit 38 has cars 50 and 51 which cooperate with'either ear 17 or 18 of the regular outer units 1 as the case may be.

In order that the lower edges of units 1 and 2 will be firmly held against the previously finished wall, a depending flange'51 is formed outside of the toes 20 on the unit 1 and a similar flange 52 is formed along the bottom edge of units 2. These flanges bear against the smooth outer and inner surfaces of the completed wall. See Figs. 1 and 4.

Should it be desired to control both of the set screws of a unit aligningclamp simultaneously, they may be adapted to this purpose as shown in Figs. 11 and 15 wherecn a shaft 53 is mounted along the top of the clamp 64 in bearings 54. At each end of the shaft sprocket hand wheels 55 are attached. Each of the adjusting screws 56 has asprocket wheel 56, larger or smaller as desired and chains 57 connect wheels 55 and 56. To easily move the clamp in adjusting it for alignment, handles 58 may be attached to any one or .all of the sprocket wheels.

Whenever an irregular design is desired for the outer surface'of a wall, it may be made after the order of Fig. 16 in which two units 59 are shown. These have irregular, though related geometric outlines, whose Whole included area is the same as that of the dotted squares 60. These units have ears 61 which serve a purpose similar to cars 17 and 18 in holding adjacent units secured to each other. YVherever the outline is found within the dotted squares its exact counterpart in area is also found on the outside of the dotted lines 60 thus making the area of an irregular bordered unit the same as though it were quite square or rectangular. may be made in any desired design that will harmonize with the arbitrary irregular exterior border. These units will fit equally well when inverted.

Fig. 7 illustrates the fine material exterior at 62 and the coarser interior at 63. This relation may be varied at will, but I desire to protect the process of forming a concrete wall with a contrasting finish exterior made homogeneous with the interior.

A very important feature of my invention lies in being able to quickly and accureately adjust the units into vertical alignment by 'moving the two screws of each clamp in the same direction simultaneously when the upper edges of the units will be drawn either inward 0r outward as desired, at all times retaining the same wall thickness. as shown by the dotted vertical lines of Fig. 8.

With my improved method of building, artistic exteriors are possible which cannot filled up afterward with cement.

The interior design of these units easily be recognized as differing from the finest executed brick walls. The process is self repetitive in that the configuration left inany completed unit course, lengthwise and vertically ofthe wall co-operates with tally.

or registering portions of the different units. The forms are so easily set up that unskilled labor can be advantageously employed. Supervision need not be continuous, as aline stretched from corner to corner along the thickerpart 63 of the wall composed ofcoarse concrete made water proof if desired, 1

is filled in up to the top of the units which when set the form units are removed by takmg away the rods 27, 1f used, and loosening the clamps and removing pins 19 for reassembling. to form a new course. The tiny til) all

holes formed by rods 27 through the wall are Proposals of this character heretofore made do not readily lend themselves to the production of aesthetic and artistic exteriors,

because of the inability to duplicate the finest brick work.

As this invention is of commanding importance I desire to cover its features in an adequate manner, hence the system is claimed in its broadest manner regardless of modifications oradaptations thereof, for instance the inclusion of an air space in the wall by any suitable means, not shown, is equally included within the broad concept of the invention.

Whenever the words vertical and perpendicular are used in the claims, their meaning is not confined to the exact geometrical definition, as any wall though departing from a true vertical direct-ion will come within the scope of my invention.

lVhat I claim is:

1. A form clamp for holding retaining plates spaced apart at a fixed distance to establish the inner and outer wall surfaces in perpendicular alignment comprising a U- shaped member, adjusting screws near the extreme end of the member, and pivoting notches formed on the under edge of the connecting portion of the U-shaped member adapted to hold the retaining plates spaced apart at a predetermined distance during the manipulation of the said screws.

2. In building forms, a pair of retaining plates, means for holding them in fixed spaced apart relation at their bottom edges, unitary means for simultaneously engaging the upper edges of the plates in an adjustable manner Without Changing their relation llli at the bottom edges so that during the alignment of the plates their spaced apart relation is retained.

3. A form clamp having two projections from the body thereof, limiting lugs on the under side of the body adapted to define pivotal points for form units, and means located near the termination of such projections for simultaneously aligning the oppositely positioned form units.

4. In building forms, a pair of retaining plates, through bolts engaging the plates near their bottom edges adapted to hold them against pressure on their adjacent faces, and unitary clamping means for simultaneously and adjustably engaging the upper edges of the plates to align the Wall.

5. In building forms, outer retaining plates placed end to end, pins for removably holding the plates in engagement with each other, inner retaining plates, means for positively holding the inner and outer plates spaced apart at their bottom edges comprising through bolts Whose ends are secures to said plates, means for pivotally supporting the plates in spaced apart relation at their upper edges, and means for simultaneously adjusting both the inner and outer plates to align the Wall vertically.

6. In building for-ms, exterior retaining plates having configurations on their inner faces and irregular adjoining edges, means for reinovably holding the plates in end to end relation, and projections from their up per edges forming bearing points for retaining clamps.

7. In building forms, exterior retaining plates having irregular adjoining edges, means for reinovably holding the plates in edge to edge relation, and unitary retaining clamps for both plates adapted to pivotally engage their upper edges.

8. A form clamp for holding retaining plates spaced apart to establish the inner and outer surfaces of a Wall comprising a U- shaped unitary member, adjusting screws near the extreme ends of the member, and means for pivotally engaging the inner edge of the unitary membe With the top edges of the plates to hold them in spaced apart relation at a predetermined distance during the manipulation of the screws.

In testimony whereof I afiix my signature.
